20 Extreme Parallelisierung Lookup Tables Flash Controller FPGA** FLASH Media Write Buffer I/O Interface CPU CPU RAM Increases the number of flash chips that can run concurrently Done by increasing the number of flash chip controllers Each TMS flash chip controller can do 36 4KB DMAs* in parallel (40 if you include the background chip RAID, or VSR, operations) A RamSan-70 has 8 controllers, so it can do 288 4KB operations simultaneously A RamSan-810 has 40 controllers, so it can do KB operations simultaneously *DMA = Direct Memory Access **FPGA = Field Programmable Gate Array
